Description:
The DIH-137 is a State-of-the-Art Photovoltaic Solid State Relay designed for 28V AC-DC Aircraft power applications
where package space-efficiency and high reliability are critical.
Each package contains two independent N/C relays, with separate LED inputs and optically isolated power MOSFET
outputs. The Normally Closed (N/C) outputs are able to operate AC or DC.
Each relay, A or B, is capable of carrying 150mA DC continuous current and 250mA DC peak current. Each LED
optically couples to a Photovoltaic (PV) IC chip which responds by generating a voltage. This voltage is internally
connected to the Gate and Source terminals of the output MOSFETs, thus controlling their current. The DIH-137 is also
available screened to military specifications, as required.
